I has compiler "unknown error" in IntelliJ IDEA 2017.1.2 regularly the same like at this issue
#32
In project more than 10 classes with [Bindable] metadata. In some classes more than 20 public properties for this reason I don’t want to use manual PropertyChangeEvent.PROPERTY_CHANGE dispatching.
I try to import starling.events.EventDispatcher in each class, try to switch off "Compile independent modules in parallel" (in project one AS-library module) but still has compiler "unknown error".
Feathers SDK v 3.3.1 with AIR 27.0 SDK.
Added simple project files as you asked. When I remove [Bindable] in several classes then all is fine. Looks like too much [Bindable] metadata in project. Perhaps this is why earlier compiling was without errors.
